Modern mobile devices have long ceased to be just means of communication, turning into powerful workstations that users carry in their pockets. However, one of the main problems remains the inability to effectively work with several tasks simultaneously, as is common on personal computers. Many smartphone owners do not even suspect that their device supports a function split screenthat allows you to run two applications side by side.
Activating the dual-window mode radically changes the experience of using the gadget, allowing, for example, to watch a video while chatting in the messenger or copy text from the browser directly into notes. The implementation of this function depends on the specific version of the operating system Android and the manufacturer's proprietary shell, be it Samsung One UI, Xiaomi MIUI or pure Android from Google.
In this article we will analyze in detail all the existing ways to activate multitasking, from standard gestures to hidden features for advanced users. You will learn how to properly adjust the size of windows, which applications support this mode, and how to avoid common mistakes when working with a split display.
Built-in split-screen capabilities in Android
Starting with version Android 7.0 Nougat, the multitasking function has been implemented directly into the kernel of the operating system. This means that most modern smartphones released over the past few years are technically capable of displaying two active windows without installing third-party software. However, manufacturers often hide this option or change the way it is activated.
The standard algorithm of actions usually involves using the recent applications menu. You need to launch the first application, then go to the overview of open tasks and find the application icon icon at the top of the window. Clicking on this element opens a context menu where you can select Split screen or Split Screen.
After this, the upper or left part of the display will be assigned to the first app, and the lower part will offer to select the second application from the list of recently used ones. If the app you need is not in the list, you can open the full list of installed applications and launch it from there. You can drag the border between windows with your finger, changing the proportions of the occupied space.
It is worth noting that not all apps are optimized for working in this mode. Some developers block the ability to resize the window, believing that their application must occupy the entire screen to display the interface correctly. In such cases, the system may issue a notification that the application does not support separation.
Features of working in shells from different manufacturers
Chinese and Korean vendors often modify the standard behavior Android, adding their own unique features to increase productivity. For example, devices Samsung have one of the most advanced implementations of multitasking called Multi Window.
Owners of flagship models Samsung Galaxy can use not only split the screen in half, but also run applications in the form of floating windows on top of other apps. This allows you to have three or more applications open at the same time. Activation is done through the Edge Panel or by long pressing the "Recent Apps" button.
Smartphones Xiaomi and Redmi offer the "Floating Windows" feature in the multitasking menu. By holding your finger on the app thumbnail in overview mode, you can select the option to make the window floating. Also in some versions MIUI a three-finger swipe down gesture is available to quickly activate a section of the screen.
Samsung DeX secret function
If you connect a compatible Samsung smartphone to a monitor or TV via USB-C, the interface will turn into a semblance of a Windows desktop, where you can open dozens of windows simultaneously, like on a full-fledged one PC.
Devices from Huawei and Honor also have their own implementation option, often called “App Multiplier” or simply split screen, which is activated through the control panel or a special gesture with two fingers spread apart diagonally along the screen.
⚠️ Attention: Shell interfaces are updated regularly. Menu items may be named differently or moved to other settings sections. If you do not find the described functions, check for system updates or look for information specifically for your model in the official user manual.
Third-party applications for creating a second screen
If the built-in functions of your smartphone do not meet your needs or the device is running on an old version Android, help specialized applications come from the store Google Play. These utilities emulate the operation of a split screen by creating containers for running applications.
One of the popular solutions is an application Split Screen Shortcut. It creates a widget on the desktop that, when clicked, allows the user to select two applications to run simultaneously. This is especially convenient for devices where the manufacturer has disabled native support for the function.
- 🚀 Floating Apps — allows you to launch multiple instances of browsers, calculators and notes in the form of independent floating windows.
- 📱 Parallel Space — creates an isolated space where you can clone applications and run them in parallel with the main ones (useful for two accounts on social networks).
- 🖥️ Taskbar —Adds a Windows-style taskbar to the screen, making it easier to switch between windows and launch applications in split-screen mode.
Using third-party software has its drawbacks. Such applications consume more RAM and can drain your battery faster as they are forced to constantly render multiple active processes. In addition, some banks and protected applications may not run inside such containers for security reasons.
☑️ Check compatibility before installation
Setting up gestures and hotkeys
For the most comfortable work with two screens, it is critical to set up quick switching methods. Manually calling up the menu each time takes a lot of time, so it’s worth taking advantage of the interface customization options available in the system settings.
In the section Accessibility many smartphones you can find settings for controlling gestures. For example, you can assign the Split Screen action to a long press of the Home button or to swiping from the edge of the screen. On devices with navigation buttons, a combination of long pressing the task overview button often works.
For users who prefer touch controls without physical buttons, there are navigation gestures. In the clear Android you can swipe up from the bottom edge of the screen to enter multitasking mode, then select the app you want to share.
⚠️ Attention: When assigning complex gestures, make sure they don't conflict with system commands. Accidentally triggering a gesture while playing a game or watching a video can interrupt the process and lead to loss of progress.
Some advanced launchers, such as Nova Launcher or Microsoft Launcherallow you to create your own gestures for application icons. You can configure it so that double-clicking on the messenger icon immediately opens it in the top split-screen window.
Limitations and system requirements
Despite its apparent simplicity, the dual-screen function places certain requirements on the smartphone's hardware. The main limiting factor is the amount of RAM (RAM). For comfortable operation of two heavy applications, for example, a browser with many tabs and a navigator, it is advisable to have at least 4 GB of free memory.
On budget devices with 2 GB or 3 GB of RAM, the system can force close one of the applications when switching focus to free up resources. This is called "killing background processes" and is normal behavior to optimize performance Android on weak hardware.
| RAM volume | Performance in 2-window mode | Recommendation |
|---|---|---|
| 2 GB | Low, frequent application reboots | Use only lightweight utilities |
| 4 GB | Average, stable operation of most tasks | Optimal for everyday use tasks |
| 6 GB or more | High, smooth operation of heavy games and videos | Full multitasking without restrictions |
If your smartphone starts to slow down when working with two screens, close all unnecessary tabs in the browser and stop background processes in the developer settings.
It is also worth considering the screen resolution. On devices with a small diagonal (less than 5.5 inches), using two applications at the same time can make the interface unreadable, as the controls will become too small. In such cases, it is better to use the floating window mode instead of a hard split in half.
Advanced methods via USB debugging
For enthusiasts and developers, there is a way to force split-screen mode for applications that do not officially support it. This is done through the developer menu and requires connecting the smartphone to the computer or using special terminal emulators directly on the device.
You must activate the developer mode by clicking seven times on the build number in the section About the phone. Then in the developer menu you should find the item Force resize actions (Force activities to be resizable). After enabling this option and rebooting the device, the system will allow you to stretch the windows of any applications.
adb shell wm size 1080x1920
adb shell wm density 480
Using commands ADB (Android Debug Bridge), you can emulate the presence of a second screen or change display parameters. However, this method requires caution: incorrect commands may cause the interface to become unreadable, requiring a data reset or reconnection to the PC to restore settings.
⚠️ Attention: Tampering with system settings through debugging may break some applications, cause interface glitches, or lead to system instability. Use these methods only if you understand the risks and know how to roll back changes.
Forcing window resizing is a powerful tool, but it does not guarantee the correct operation of the application interface that has not been adapted by the developer for multi-window mode.
Frequently asked questions (FAQ)
Why is the "Split Screen" button inactive or missing?
This can happen for several reasons: the application does not support multitasking, the smartphone has less than 2 GB of RAM, or the function is disabled in the system settings by the manufacturer. Try updating the application or checking the settings in the "Default Applications" section.
Is it possible to run the same game in two windows?
You cannot run two instances of the same application at the same time using standard Android tools. This requires special application cloning functions built into Xiaomi, Samsung or Huawei shells, or the use of third-party utilities like Parallel Space.
Does dual-screen mode affect battery consumption?
Yes, working with two active applications significantly increases the load on the processor and screen, which leads to accelerated battery drain. The processor is forced to process graphics and data for two apps at the same time, and the screen operates at high brightness over a larger area.
How to exit split-screen mode?
To close the mode, find the dividing bar between the windows and drag it to the very top or bottom of the screen (depending on the orientation). Or press the Home button to minimize both applications, or the Back button if it is configured to close the current focused window.
